<b>Update on Management of Placenta Previa and Placenta Accreta Spectrum</b>

<i>Placenta previa is a major risk factor for postpartum hemorrhage and can lead to morbidity and mortality of the mother and neonate. This situation prevents a safe vaginal delivery and requires the delivery of the neonate to be via cesarean delivery. The presence of placenta previa can also increase a woman's risk for placenta accreta spectrum (PAS).</i><b><i>Objectives</i></b><i>:</i><i> </i><i>In this article; we aimed to review the update on management of placenta previa and placenta accreta spectrum, </i><b><i>Methods</i></b><i>: These databases were searched for articles published in English in 3 data bases [PubMed – Google scholarscience direct] and Boolean operators (AND, OR, NOT) had been used such as [Diagnosis of Placenta Accreta and Placenta Accreta Spectrum OR PAS] and in peer-reviewed articles between June 2005 and February 2023. Documents in a language apart from English have been excluded as sources for interpretation was not found. Papers apart from main scientific studies had been excluded: documents unavailable as total written text, conversation, conference abstract papers and dissertations. </i><b><i>Conclusion</i></b><i>: The timely diagnosis of abnormal placentation is of great importance since, the earliest diagnosis implies less risky, less costly and successful management. Ultrasonography may successfully achieve this goal. Furthermore, MRI imaging, in cases of diagnostic dilemmas may be particularly useful and lead to safer and more precise diagnosis</i><i>DOI:10.6084/m9.figshare.24201264</i>
